Multiple studies consistently demonstrate that volcanic eruptions inject aerosols into the atmosphere, which reflect solar radiation and lead to significant surface cooling.
The retrieved papers provide robust support for the claim that volcanic eruptions cool the Earth's surface through the injection of aerosols that reflect solar radiation (or increase cloud reflectivity). Papers [0], [1], [3], [5], [7], and [9] explicitly discuss the surface cooling and radiative forcing mechanisms resulting from volcanic aerosols. None of the provided papers refute the core claim.
